[0:12]Shelcy, look at my test paper. I scored 40 out of 50. Is that good? Hmm, sounds good, but let's find out exactly how good. We need to calculate your percentage! Percentage? Oh no. Mathematics. Can't I just guess? Nope! But don't worry, percentages are super useful and easy once you understand them. A percentage is a way of showing how much something is out of 100. Imagine a store keeping 100 shirts. If you buy 25, you bought 25% of the shirts. Oh! So if I buy 50 shirts, I bought 50%? Exactly! We use percentages in discounts, test scores, sports and even battery levels on your phone. Here's a simple way to calculate a percentage. Percentage multiplied by total divided by 100. Example: 25% of 200. 25 multiplied by 200 divided by 100 equals 50. So 25% of 200 is 50! That's not hard. Now, let's find your test score percentage. You got 40 out of 50. We use the formula: marks scored divided by total marks multiplied by 100. 40 divided by 50 multiplied by 100 = 80%. Whoa, I scored 80%. That sounds great! Yes! And now, you can compare scores easily. For example, someone who scored 30 out of 50 would have: 30 divided by 50 multiplied by 100 equals 60%. So I scored higher. Percentages are fun! That's it! You can find percentages anywhere. Try this. What is 20% of 150?
